PIPE- CLEANER.

Specification of Letters Patent.

Patented May in, rain.

Application filed October 28, 1909. Serial No. 525,210.

To all whom it may concern:

Be it known that I, HORACE P. STEWART, a citizen of the United States,residing at Armstrong Creek, in the county of Forest and State ofWisconsin, have invented certain new and useful Improvements in Pipe-Oleaners, of which the following is a speci fication.

My invention relates to improvements in implements for cleaning the coaland smoke accumulations from the inside of smokers pipes, and its objectis to provide an implement for the purpose stated, that will beconvenient to carry, to use and to thoroughly clean the inside of asmokers pipe, and which Will, at the same time, be inexpensive ofconstruction, thorough in its work and self sharpening. I attain theseobjects by the construction and arrangement of parts illustrated in theaccompanying drawing, in which Figure l is a plan of the blank fromwhich the implement is made. Fig. 2 is a perspective of the blank benton the line 0 cl of Fig. angled wings. Fig. 3 is the same bent on thelines a, a, and b to form the top and handle of the implement, and Fig.A is a perspective of the implement shown in a vertical section of apipe bowl.

Similar letters refer to similar throughout the several views.

This implement is made of thin sheet metal, preferably of steel, and isformed by first making a blank, as shown in Fig. l, and then bendingsaid blank upon the lines o d to form the body or right angled wings C,and upon the lines a, b, c, to form the upper end B and the handle A.This so forms the implement that the edges, C, of the body 0 will be inposition to scrape upon the inner surface of the pipe bowl D and removeany substance that may be deposited thereon, when the implement is madeto re volve in either direction, that is, to the right or to the left,by exerting force upon the handle A. The ashes, coal and othersubstances of which the coating of the pipe is composed, is of such anature that when the implement is turned to the right the effect uponthe left hand Wing of the implementwill be to keep it well polished andthe outer edge C sharp, so that when the implement is once made andsharpened, and is kept in use, there will never be any necessity ofresharpening it, and the peculiar parts 1 to form the body or rightshape given it by bending it upon the line (Z renders it available forthe purpose for which it is made until the wings are well worn towardthe center line (Z.

To clean a pipe with this implement, the implement is placed in the bowlD of the pipe and the point of the implement forced down to the bottomof the bowl, with the edges G and the apex of the right angle formed bythe converging wings C C resting firmly against the inner surface of thebowl, or the coating that covers said inner surface, and the implementis held by gripping the handle A with the thumb and finger and turningit to the right or to the left, or both, as the case may be, though Ifind it much more satisfactory to continue to turn it in one directionwhen once started. As hereinbefore suggested, it should be turned in onedirection at one time and in the other direction at other times so thatthe edges may be kept sharp to cut the deposit from the bowl, perfectlywithout the necessity of grinding or otherwise sharpening them apartfrom their normal use.

The wings C C that form the body of the implement should be made upon a,practically, true taper from their point of conjunction with the end Bto near the point, from which point they should be made to conform veryclosely to the rounded form of the bottom of the bowl, so that theywill, after use a few times, conform to the form of bowl.

That I claim as new, and desire to secure by Letters Patent of theUnited States, 1s:

1. A pipe bowl cleaner constructed from a single piece of sheet metalcut and bent to form a tapering body having two wings set at rightangles, a back bent up integral therewith, and a handle formed integralwith, and projecting back from said back.

2. A pipe bowl cleaner made from a single piece of sheet metal cut andbent to form a body having a back and a handle integral therewith, saidbody tapering from the back to the point and having two wings standingat right angles with the edges formed thereby in such position as toform cutting edges for the surface of the pipe bowl.

3. A pipe bowl cleaner composed of a single piece of sheet metal cut,bent and formed to make a body having wings that stand at right angles,a back and a handle formed integral therewith, said wings being soformed that when the cleaner is made to revolve the edge of one WingWill cut the deposit from Signed at Grand Rapids Michigan Octothe innersurface of the bowl and the deposit her 26, 1909.

in the bowl will )01ish anc shavr en the ec e of the other win g, saidwings made to tap er HORACE STEVART' from the back to near the point ofthe body In presence of and thence to curve to the point, substan-ITHIEL J. CILLEY,
